Novel insights into an old phenomenon: the no reflow

Coronary artery diseases and particularly acute myocardial infarction are the leading causes of mortality and morbidity inwestern countries. Despite the achievements of the last decades with the advent of double antiplatelet therapy, new antithrombotics and reperfusion strategies (either pharmacological or mechanical), many patients still have adverse cardiovascular events after ST-segment elevation acute myocardial infarction; at least some of these adverse events are related to the no reflow phenomenon that occurs after primary percutaneous coronary intervention. In our review we will discuss the various aspects of this phenomenon. (C) 2015 Elsevier Ireland Ltd. All rights reserved.
